Yup, and Google bought outright the old Port Authority building in Chelsea (west side of Manhattan for the innocent). 111 8th Ave. That one. The whole thing. This is a BIG ASS building. It doesn't go UP like normal big buildings in Manhattan but it goes OUT forever and ever. The crosstown long blocks are even longer around there, and the thing takes up a whole one. I measured it on Google Earth just for grins, and it's almost a quarter mile. In Manhattan, that's a lot of real estate.
The L.A. mall in question was quite the thing when it first opened. It was drooled over by architecture critics. It had two huge anchor stores. It all fell apart at some point. They raised the rent at a bad time, a lot of places left, including both anchors, and from then on it was waiting to die.
I hope for the sake of the planet that LA shopping centers' coating of that architecture critics drool doesn't prevent Google from buying it for the land with the intention of leveling it to the ground. Insofar as leaving an energy footprint those malls are comparable to coal powered steam. They can't be fixed without razing them to the ground and starting over.
I don't know about heating, cooling, and lighting systems for that old Port Authority building in Chelsea. If it looks like a several story tall blocks size rectangle from the outside it's probably salvageable.
